If you decide to create an app, you should consider the goal and target market of the app, research your niche and competitors, and make a plan.
Consider the Goal and Target Market
Start with a pen and paper and write down the goal for the app. Know what you want the app to accomplish. Determine who the app is for as well.
Do Your Research
Determine the characteristics of your target market. Look into their interests, their taste in fashion, colors, music, and the like.
Next, find out what your competitors are doing. Check out their designs, navigational structures, and functionalities.
Make a Plan
As long as you know your goal and target market, create a plan on how to achieve the ideal design for your app.
Do not just come up with an app idea. Learn how to design an app as well.
